Alignmed SpinalQposture garment, which he credits with
maintaining good posture on cross-country hauls.
- Place feet flat on the floor and adjust seat height until knees are bent at a 90-degree angle. Knees should not be higher than hips.
- Filling the lumbar support so it meets the back should provide “a firm yet comfortable level of support… Good lumbar support will minimize slouching (forward head positioning) and will dampen the exposure to vibration.” However, be aware that overfilling lumbar bladders can cause rounding of the spine.
- Slightly reclining the seat back is recommended. Adjust seat distance fore and aft to make sure each pedal can be depressed without raising or rotating out of the seat.
- Seat-pad depth is correct if at least two fingers can be placed between the back of the knees and front of the seat pad by lifting it and moving it in or out.
- Seat pan can be tilted by tall drivers so the front of the seat meets the knees. When driving conditions require high clutch use, drivers may consider lowering the front of the seat pan.
- Release the fore‐aft lock so the seat can float and absorb some of the cab movement in city driving or if trailer is pushing and tugs cab.
- Steering wheel should be adjusted to meet the driver with hands at 9 and 3 o’clock positions. Elbows should be close to driver’s sides and he or she should avoid having to reach to meet steering wheel.
- Mirrors should be adjusted so complete area of each mirror can be seen without slouching or twisting. And mirrors can serve as “a cue to sit up when you slouch instead of readjusting them.”
